I am using jqMath to display chemistry formulas on a website. I need to be able to display charges as superscripts (i.e., positive + and negative charges -). It seems like jqMath (or maybe MathML) hardcodes all math operators to display as normal size. I’ve tested this with +, -, =, and % signs and none will display as superscripts (tested here: http://mathscribe.com/author/jqmath.html). Note that 

<sup></sup>

is not valid markup when using jqMath; the ^ precedes any character to be superscripted.

Has anyone found a way around this?

    Enclose the superscript in {}: $H^{+}$ (or $\H^{+}$ to avoid italics).
